Tips and warnings

  • With DS2Key, you can also use the DS's touchscreen in place of your PC's mouse.
  • The DS's four-button game pad is well-suited for classic two-dimensional computer games.
  • DS2Key version 6.0, the latest version as of 2011, only works for single player games.
  • DS2Key only works with wireless Internet connections, as it relies on the DS's Wi-Fi compatibility to operate.
